Blood leakage from the eyeball may be caused by blood diseases or vascular lesions, eye trauma, etc. It is recommended that people with related manifestations should consult a doctor in time to clarify the cause of the disease and take active treatment. 1. Hematologic or vascular lesions: they are the most common causes of ocular hemorrhage. The common causes are some congenital and hereditary diseases, such as hemophilia, familial purpura, congenital and histiocytosis, and hereditary hemorrhagic capillary dilatation disorder, which will lead to spontaneous hemorrhage or intraocular hemorrhage after mild injuries. 2. Ocular trauma: that is, when the eye is hit by blunt objects, sharp cuts, high-pressure gas or liquid impact and other conditions, it will cause the eye to suffer from contusion, cuts and other traumatic injuries, which will lead to localized rupture of blood vessels leading to ocular hemorrhage manifestations. It is recommended to consult a doctor promptly after the symptoms of unexplained eye pain, rapid vision loss, corneal discoloration, and dark shadows in front of the eyes.
